Retirement tax questions

A 2018 1099-R with a code P must be reported on  an amended 2017 tax return - using the 2017 software is correct.  The "which year" question is after you enter the 1099-R so don't worry that it says on the entry screen that code P is 2016 - that will change to 2017 on the next screen.  However, if the taxable amount is only 6 cents, then ignore it since any amount less than 50 cents rounds to zero and zero taxable amount is not allowed.
